f Be it known that I, VJ W. LARIMORE, of Chicago, in the countyA of Cook, inthe State .of Illinois, have invented a useful Improvement in Lamp-Chimneys; andY I do hereby declare that the following vis a full and exact description thereof, reference being had to the `acecmparif'ngdrawings, and to the letters of reference marked thereon, making a part of this specification, in which- Figure 1 is a'perspective representation of my inven-4 tion.' Figure 2, an elevation of the top section of the chimney, removed from the lower para 'Figure 3, an elevation of one of he frames, and the glass therein, removed from the other parts.

Figure 4, a view of the spring, which'holds one of Figure 5,'a top view of -the lamp-burner, showing the' lugs which hold the chimney in place.

This invention relates to an improvementn that class of lam himneys which are made of several pieces, and arranged to be taken apart, for cleaning, repairs, 85o.; and y Its nature, in general terms, consists in a two-part the top section of which is made of isinglass, whose bottom end has spring-fast.- which hold the glass sides of the' lower section in position, and it also has hooks, to which the top ends of the. lower frames are fastened; and in a novel construc-v tion of the chimney-base, whi h has flanges and springs enings,

' attached for holding the lower ends of the glasses and frames in place.

By means of this arrangement, the chimney can be taken apart,cleaned,' and put together in less time than the common onel can be cleaned; and if any glass isbroken, it can be readily replaced by a gla'zier; and, as a whole, for continuous-use, is cheaper than chimneys made wholly of glass.

To enablethose skilledin the art to fully comprehend the construction and application of my invention, I have marked corresponding parts with similar letters, andwill now give a detailed description. Z, g. 1, represents a metal base-plate, which has a series of apertures or holes through it, for the passage lof air, and a central opening, in which the burner O figs. 5 and 6, is placed, and it on its opposite sides, as seen at the lower ends of the glasses a: x in position.

And in the plate are made notches fv m n, which ex-A tend outward fromthe main opening, and ypermit the lugs U S T, attached to the burner, (iig. 5,) to pass through andhold the chimney in position. This latterarrangement, however, having been used, is, therelfore, no part of my invention.

The cone L is made a part of the plate M, iig. l,

and is supported, a suitable distance from the plate Z,

to suit the size of the burner, by four metal pedestals, \N N, 86o., and securely attached to bothplates.

W, iig. 1, which' holds This means of supporting the cone is foundto communicate the least amount of heat to the lamp, for the reason that the connections between M and Z are located attheextreme corners of the air-chamber; consequently the atmosphere passing through the same keeps. the lower plate cool, and thus greatly tends to prevent explosion.

A0 D represent the-top section of the chimney, which is constructed. in the form of a truncated pyra mid, with its sides illed in with thin plates of isinglass, (rnica,) leaving a suitable passage for smoke and heat to escape. f of thin metal, the angles of which hold 'the isinglass in place, said frame also having two'lugs FF projecting downward from the bottom, for holding in position vthe tops of the lower glasses a: a: on one side, and springs G G for snpportingfthem on the other side, the other two sides having hooks E E, figs. 1 and-2, which support the tops of thelowerframes I I. r p

These frames are made of thin metal, and have grooves, which support thin plates of isinglass, as shown at Y, iig. 3, and they have loops H H at the top, whichfasten over the hooks E E, and also hooks J J, at their bottoms, which receive the ends of 4wire springs k k, designed to hold the frames in position at the bottoms. Said springs have apeculiar form, as shown at iig. 4, and are looped through the 'plate Z, as shown atiig. 1,*Which method of fastening is very simple, convenient, and substantial.

In order to attach the chimney to the burner, the lugs U S, iig. 5, should be put through the notches o m, fig. l, and the chimney turned to the left, which will bring the lug T into the notch n, the .lugs U S bearing on the top of the plate Z, and the lug T preventing the chimney from being displaced when in use'. When the chimney is to be cleaned, the ends of the spring k k shouldbe lifted out of the hooks J J, and

has a flange or projection I the loops'H H removed from the hooks E E', which operation will permit the top section to be removed, and loosen the'glasses w x.

The wick can be lighted either chimney or one of the frames I I.

Having thus fully described my invention,

What I claim, -ent of the United States, is-

1. The combination of the springs kh, looped through the plate Z, hooks J J, and frames I I, as herein shown and speciiied.

2. The frames I I, glasses x x, in combination with the top section A B O D, constructed andarranged as and for the purposeset forth.

3. The combination of the plate Z, cone L-M, pedestals N N, glasses :t x, frames I I, and top section A B O D, substantially as herein shown and specified.
